(mounting of Process Cartridge)

As shown in fig. 1 and 2, the process cartridge 101 includes a developing unit 2 and a photosensitive unit 3 which are separated from each other, a developing member 22 rotatably supported on the developing unit 2 is provided in the developing unit 2, and a photosensitive member 33 rotatably supported on the photosensitive unit 3 is provided in the photosensitive unit 3. A first power receiving unit 23 and a second power receiving unit 32 are further provided at one end of the developing unit 2 and the photosensitive unit 3 in the longitudinal direction (direction parallel to the Y direction) of the process cartridge 101, respectively, the first power receiving unit 23 including a first power receiving part 24 and a first boss 25, the second power receiving unit 32 including a second power receiving part 34 and a second boss 35, and a first driving part 15 and a second driving part 14 are further provided in the main body 10 in correspondence with the first power receiving part 24 and the second power receiving part 34. Further, a first guide rail 11 and a second guide rail 12 for mounting the photosensitive unit 3 and the developing unit 2 are also provided in the main body 10. When the photosensitive unit 3 and the developing unit 2 of the process cartridge 101 are mounted into the main body 10 along the first guide rail 11 and the second guide rail 12, respectively, the first power receiving member 24 and the second power receiving member 34 are engaged with the first driving member 15 and the second driving member 14, respectively. When a motor (not shown) provided in the main body 10 rotates the first driving member 15 and the second driving member 14, the first power receiving member 24 and the second power receiving member 34 also rotate together, and rotate the developing member 22 in the developing unit 2 and the photosensitive member 33 in the photosensitive unit 3, thereby performing a developing operation.

The developing unit 2 is further provided with an acted portion 21 and an elastic member (not shown), the acted portion 21 is swingable relative to the developing unit 2, and an elastic force is applied to the acted portion 21 by the elastic member to swing the acted portion 21 to a set position relative to the developing unit 2.

As shown in fig. 3, an action lever 13 acting on the acted portion 21 is provided in the main body 10, and is driven by a motor or other driving mechanism provided in the main body 10 so as to be displaceable in the X direction or in the reverse direction of the X direction, and one end of the action lever 13 in the X direction is provided with a pulling portion 131 and a pushing portion 132 projecting upward. The second guide rail 12 provided in the main body 10 is rotatably supported on the inner wall of the main body 10 by a support shaft 16.

After the developing unit 2 and the photosensitive unit 3 are mounted in the main body 10, the pulling portion 131 of the action lever 13 is brought into abutment with the acted portion 21 by controlling the action lever 13 to move in the X direction, thereby pushing the developing unit 2 to swing about the rotation shaft in the counterclockwise direction to a position where the developing member 22 of the developing unit 2 is brought into abutment with the photosensitive member 33 of the photosensitive unit 3, and the first power receiving member 24 provided on the developing unit 2 is engaged with the first driving member 15 provided in the main body 10. Thereafter, the action lever 13 continues to push the acted-on portion 21, causing the acted-on portion 21 to swing in the X direction with respect to the developing unit 2 until the pulling portion 131 passes over the acted-on portion 21, and the acted-on portion 21 swings in the X direction in the reverse direction to the set position by the elastic member. At this time, the acted-on portion 21 is located between the pulling portion 131 and the pushing portion 132. When the action rod 13 is controlled to continue moving in the X direction, the pushing portion 132 of the action rod 13 abuts against the acted portion 21, so that the developing member 22 of the developing unit 2 is kept abutting against the photosensitive member 33 of the photosensitive unit 3, and the electrophotographic apparatus starts operating.

When the electrophotographic apparatus exits from the operating state, after the action rod 13 is controlled to move a distance in the direction opposite to the X direction, the pulling portion 131 of the action rod 13 abuts against the acted portion 21 of the developing unit 2, and pulls the developing unit 2 and the second guide rail 12 to rotate around the supporting shaft 16 in the clockwise direction, so that the developing member 22 of the developing unit 2 is separated from the photosensitive member 33 of the photosensitive unit 3, and the developing member 22 is prevented from deforming due to long-time contact between the developing member 22 and the photosensitive member 33, and the developing quality of the process cartridge 101 is prevented from being affected. At this time, the first power receiving member 24 is disengaged from the first driving member 15.

Example one

The embodiment provides an electronic imaging device, which comprises a main body and a detachable processing box arranged in the main body, wherein a power receiving part is arranged on the processing box, and a detection device is also arranged in the main body and is used for detecting the processing box by detecting the movement of the power receiving part, namely, whether the processing box is arranged in the main body in place or not is detected, or whether the model of the processing box arranged in the main body is matched with the model of the electronic imaging device or not is detected.

The following description will be given taking an example in which the detecting means detects whether the developing unit 2 is mounted in place in the electronic image forming apparatus main body 10.

As shown in fig. 5, the third power receiving unit 70 is provided at one end of the developing unit 2 in the Y direction, and includes a third power receiving member 74 and a third hub 75, the third power receiving member 74 being engaged with the first driving member 15 when the developing unit 2 is mounted in the main body 10. The third power receiving member 74 and the third hub 75 may be connected by a universal joint, that is, the third power receiving member 74 may swing in any direction relative to the third hub 75. The third hub 75 may be directly connected to the developing device 22, or the third hub 75 may be engaged with a gear set disposed at one end of the developing unit in the Y direction through a gear on the surface of the third hub 75, so that the third hub 75 can drive the developing device 22 in the developing unit 2 to rotate. A pair of power receiving claws 742 are provided at one end of the third power receiving member 74 in the Y direction, a pair of power transmission projections 151 protruding in the radial direction are provided at the opposite end of the first driving member 15 in the Y direction, and after the third power receiving member 74 is engaged with the first driving member 15, the power of the first driving member 15 can be transmitted to the third power receiving member 74 by bringing the power receiving claws 742 into contact with the power transmission projections 151.

Preferably, the detected portion provided on the third power receiving member 74 is a first flange 741 projecting in the radial direction of the third power receiving member 74. The first flange 741 is located outside the power receiving claw 742 in the radial direction of the third power receiving member 74 as viewed in the axial direction of the third power receiving member 74. Also, after the third power receiving member 74 is engaged with the first driving member 15, as shown in fig. 6, the first flange 741 is located outside the power transmitting projection 151 in the radial direction of the first driving member 15 as viewed in the axial direction of the third power receiving member 74.

As shown in fig. 4, the detecting device 40 is disposed around the rotation axis of the first driving member 15, and includes a feeler 41, an elastic member, a first conductive member 43, a second conductive member 44, and a detecting member 45. The feeler lever 41 is small in size and does not interfere with the first drive member 15 during operation. The inner wall 17 is located on the same side of the main body 10 as the first driving part 15, and a side plate 18 is further provided on one side of the inner wall 17 in the Y direction. The trolley 41 is provided on the inner wall 17 of the main body 10, and the trolley 41 is movable in the Y direction or in the reverse direction of the Y direction with respect to the inner wall 17. Preferably, the feeler lever 41 is located on one side of the first driving member 15 in the P direction (mounting direction of the developing unit 2). The trolley 41 includes a first end 411 at one end in the Y direction and a second end 412 at one end in the Y direction, and when the third power receiving member 74 engages with the first driving member 15, the first end 411 of the trolley 41 abuts against the first flange 741 of the third power receiving member 74, and moves in the Y direction with respect to the inner wall 17 by the first flange 741. At this time, the feeler lever does not have to abut against the power receiving claw 742, and the detecting device 40 and the first driving member 15 are kept at a predetermined distance, thereby preventing the two from interfering with each other during operation and deteriorating the quality of electronic forming. Therefore, when the third power receiving member 74 is engaged with the first driving member 15, the projection of the first end 411 of the trolley 41 at least partially overlaps the projection of the first flange 741 as viewed in the axial direction of the third power receiving member 74. The elastic member is provided on one side of the feeler lever 41 in the Y direction and abuts both the second end 412 of the feeler lever 41 and the side plate 18. Preferably, the elastic member is a spring 42, a first positioning post 413 is disposed on one side of the second end 412 of the contact rod 41 along the Y direction, a second positioning post 181 is disposed on a surface of the side plate 18 facing the opposite side of the Y direction, a projection of the first positioning post 413 and a projection of the second positioning post 181 in the Y direction substantially coincide, one end of the spring 42 is sleeved on the first positioning post 413, and the other end is sleeved on the second positioning post 181, so as to apply an acting force to the contact rod 41 in the opposite direction of the Y direction, and move the contact rod 41 to the set position in the opposite direction of the Y direction.

The first conductive member 43 is disposed at the second end 412 of the trolley 41, the second conductive member 44 is disposed on the surface of the side plate 18 on the opposite side in the Y direction, and the projection of the first conductive member 43 and the second conductive member 44 in the Y direction at least partially overlaps. When the feeler lever 41 is moved to the set position in the Y direction, the first conductive member 43 abuts against the second conductive member 44. Preferably, an elastic material such as sponge and rubber may be disposed between the first conductive member 43 and the inner wall 17 and/or an elastic material such as sponge and rubber may be disposed between the second conductive member 44 and the side plate 18, or the first conductive member 43 and the second conductive member 44 are directly made of an elastic conductive material, so that after the first conductive member 43 and the second conductive member 44 are abutted, the feeler lever 41 can continue to move for a distance in the Y direction to prevent the process cartridge 101 from being jammed and causing an unsmooth process.

The detecting part 45 is provided in the main body 10 for detecting a current signal, which is connected to a CPU (not shown) provided in the main body 10, and when a current passes through the detecting part 45, the detecting part 45 detects the current signal and feeds the current signal back to the CPU. The detection section 45 is connected to the first conductive member 43 and the second conductive member 44 by wires, respectively, and applies a voltage to the first conductive member 43 and the second conductive member 44 by a power source (not shown) so that a voltage difference exists between the first conductive member 43 and the second conductive member 44. When the first conductive member 43 moves in the Y direction and abuts against the second conductive member 44, a conductive loop is formed between the first conductive member 43, the second conductive member 44, and the detection member 45, that is, a current passes through the detection member 45, and the detection member 45 feeds back a detected current signal to the CPU, so that the CPU detects that the process cartridge 101 has been mounted in the main body 10. Preferably, the first conductive member 43 or the second conductive member 44 may also be provided as a varistor, thereby simplifying the entire mechanism.

The process of the electronic imaging device detecting the process cartridge 101 will be described in detail below.

As shown in fig. 5, before the third power receiving member 74 is engaged with the first driving member 15 by mounting the developing unit 2 in the main body 10, the third power receiving member 74 is swung to a set position in the mounting direction (P direction) of the developing unit 2 with respect to the third boss 75 by the torsion spring or the gravity of the third power receiving member 74, and the third power receiving member 74 is tilted toward the first driving member 15 immediately before the third power receiving member 74 is engaged with the first driving member 15. As shown in fig. 6, as the developing unit 2 continues to move in the P direction, one end of the third power receiving member 74 in the Y direction abuts against the first driving member 15, the first driving member 15 pushes the third power receiving member 74 to swing in the reverse direction of the P direction with respect to the third hub 75 to a position where the rotation axis of the third power receiving member 74 substantially coincides with the rotation axis of the first driving member 15, and the third power receiving member 74 is completely engaged with the first driving member 15. At this time, the rotational axis of the third hub 75 and the rotational axis of the third power receiving member 74 also substantially coincide.

Since the third power receiving member 74 swings in the P direction in the opposite direction to the third hub 75 under the action of the first driving member 15, the portion of the first flange 741 on the P direction side of the third power receiving member 74 moves in the Y direction and abuts against the feeler lever 41 provided on the P direction side of the first driving member 15, thereby pushing the feeler lever 41 to move in the Y direction. After the third power receiving member 74 is completely engaged with the first driving member 15, the trolley 41 is moved to the set position in the Y direction. At this time, the first conductive member 43 abuts against the second conductive member 44, thereby causing the detection member 45 to detect the current signal and feeding back the detected current signal to the CPU, causing the CPU to detect that the process cartridge 101 has been mounted into the main body 10.

Of course, the lever 41 may be swingably provided in the main body 10, and the third power receiving member 74 swings by pushing the lever 41, thereby bringing the first conductive member 43 into contact with the second conductive member 44.

Further, since the developing unit 2 can separate or contact the developing member 22 from or with the photosensitive member 33 by the action lever 13, the present embodiment can also control the developing unit 2 to move at a certain regular rate by the action lever 13, thereby causing the CPU to detect that the process cartridge 101 has been mounted into the main body 10. Specifically, for example, when the developing unit 2 is mounted in the main body 10, the movement of the developing unit 2 is controlled by the action lever 13 so that the developing member 22 and the photosensitive member 33 are sequentially in the "abutting-separating-abutting" state, the third power receiving member 74 and the first driving member 15 are correspondingly sequentially in the "engaging-disengaging-engaging" state, the detection member 45 detects that "current-no-current" is present in the sequence, and the signal is fed back to the CPU, the CPU automatically determines that the process cartridge is mounted in place, or the CPU detects that the model of the developing unit 2 mounted in the main body 10 matches the model of the electronic image forming apparatus.

Example two

As shown in fig. 7 and 8, in the present embodiment, the detecting device 40 is provided on the side of the first driving member 15 opposite to the direction P, that is, the detecting device 40 is provided on the path during the mounting of the process cartridge 101 to the electronic image forming apparatus. In the process of mounting the developing unit 2 into the main body 10, one end of the first power receiving member 24 in the Y direction abuts one end of the feeler lever 41 in the reverse direction of the Y direction and pushes the feeler lever 41 to move to a set position in the Y direction, so that the first conductive member 43 of the detecting device 40 abuts the second conductive member 44, and the CPU automatically judges that the process cartridge is mounted in place, or, the CPU detects that the model of the developing unit 2 mounted into the main body 10 matches the model of the electronic image forming apparatus. Alternatively, after the developing unit 2 is mounted in the main body 10, the developing unit 2 may be controlled by the action lever 13 to swing with respect to the main body 10 from a position where the developing member 22 abuts against the photosensitive member 33 to a position where the developing member 22 separates from the photosensitive member 33, and when the first power receiving member 24 separates from the first driving member 15, the first power receiving member 24 may abut against the feeler lever 41 and push the feeler lever 41 to move in the Y direction, so that the first conductive member 43 and the second conductive member 44 are brought into contact, and the CPU automatically determines that the process cartridge is mounted in place, or the CPU detects that the model of the developing unit 2 mounted in the main body 10 matches the model of the electronic image forming apparatus.

Preferably, one end of the trolley 41 in the direction opposite to the Y direction is provided with a tapered structure so that the trolley 41 can be pushed to move in the Y direction with a small force after the first power receiving member 24 abuts against the trolley 41.

The arrangement can lead the detection device to detect in the process of installing the processing box, thereby not influencing the engagement of the driving part and ensuring the simplicity and convenience of operation in the process of installing the processing box to a greater extent.

In addition, the developing unit 2 may be controlled to move regularly by the operating lever 13, the first power receiving part 24 contacts the contact lever 41 a plurality of times, and the CPU detects that the process cartridge 101 has been mounted in the main body 10 after the detecting part 45 detects the current signal a set number of times. For example, when the developing unit 2 is mounted in the main body 10 and the movement of the developing unit 2 is controlled by the action lever 13 so that the developing member 22 and the photosensitive member 33 are sequentially in the "abutting-separating-abutting" state, the third power receiving member 74 abuts against the contact lever 41 three times, the detecting member 45 detects a current signal three times and feeds the signal back to the CPU, and the CPU automatically determines that the process cartridge is mounted in place, or causes the CPU to detect that the model of the developing unit 2 mounted in the main body 10 matches the model of the electrophotographic apparatus.

EXAMPLE III

In this embodiment, as shown in fig. 9, the first driving part 15 and the detecting device 40 are substantially the same as those of the first embodiment, and are not described herein again.

In the present embodiment, the fourth power receiving unit 51 is used in place of the third power receiving unit 70 in the first embodiment. The fourth power receiving unit 51 includes a fourth power receiving part 52 engageable with the first driving part 15, and a fourth hub 53 connected to the fourth power receiving part 52 and capable of receiving power from the fourth power receiving part 52. The fourth power receiving member 52 is capable of extending and contracting in the Y direction or in the reverse direction of the Y direction with respect to the fourth hub 53, and the rotational axis of the fourth power receiving member 52 and the rotational axis of the fourth hub 53 are kept substantially parallel. An elastic member is provided between the fourth power receiving member 52 and the fourth hub 53, and applies a force in the Y direction to the fourth power receiving member 52 to contract the fourth power receiving member 52 to a set position in the Y direction with respect to the fourth hub 53. Preferably, the rotational axis of the fourth power receiving member 52 remains substantially coincident with the rotational axis of the fourth hub 53.

The detected portion of the fourth power receiving member 52 is a second flange 521 extending in the radial direction of the fourth power receiving member 52 and capable of abutting against the first end 411 of the feeler lever 41 when the fourth power receiving member 52 is engaged with the first driving member 15. The position of the second flange 521 relative to the fourth power receiving part 52 and the first driving part 15 is substantially the same as the position of the first flange 741 relative to the third power receiving part 74 and the first driving part 15 in the first embodiment, and will not be described again.

Further, a push rod 54 is provided at one end of the developing unit 2 in the Y direction, and when the developing unit 2 is mounted in the main body 10, the fourth power receiving member 52 is extended in the Y direction with respect to the fourth hub 53 by the push rod 54 acting on the fourth power receiving member 52 to engage with the first driving member 15. Specifically, one end (one end in the Z direction) of the push rod 54 facing the fourth power receiving part 52 is provided with a first positioning surface 541 and a second positioning surface 542, and an acting inclined surface 543 is further provided between the first positioning surface 541 and the second positioning surface 542; a third flange 523 projecting in the radial direction of the rotary shaft 522 is provided on the circumferential surface of the rotary shaft 522 of the fourth power receiving member 52. Preferably, an avoiding groove 544 is further provided at one end of the push rod 54 in the Z direction, and when the push rod 54 controls the fourth power receiving part 52 to extend and contract, the rotating shaft 522 of the fourth power receiving part 52 can be accommodated in the avoiding groove 544, so that the push rod 54 is prevented from interfering with the fourth power receiving part 52.

As shown in fig. 10, after the push rod 54 and the fourth power receiving unit 51 are mounted on the developing unit 2, the fourth power receiving member 52 is retracted in the reverse direction of the Y direction with respect to the fourth hub 53 by the elastic member to a position where the third flange 523 abuts against the second positioning surface 542, and the fourth power receiving member 52 is in the retracted position, so that the fourth power receiving member 52 does not interfere with the first driving member 15 during the mounting of the developing unit 2 into the main body 10. When the developing unit 2 is mounted in the main body 10, the rotational axis of the fourth power receiving member 52 substantially coincides with the rotational axis of the first driving member 15. When a force is applied to the push rod 54 to move the push rod 54 in the Z direction with respect to the fourth hub 53, the inclined action surface 543 provided on the push rod 54 abuts against the third flange 523 of the fourth power receiving member 52, thereby pushing the fourth power receiving member 52 to extend in the Y direction to engage with the first drive member 15. In this process, the second flange 521 on the fourth power receiving part 52 is also moved in the Y direction to abut against the feeler lever 41 and push the feeler lever 41 to move to a set position in the Y direction, so that the CPU detects that the process cartridge 101 has been mounted in the main body 10, or that the model of the developing unit 2 mounted in the main body 10 matches the model of the electronic image forming apparatus. The process of the feeler lever 41 causing the CPU to detect that the process cartridge 101 has been mounted in the main body 10 by extension and contraction, or causing the CPU to detect that the model of the developing unit 2 mounted in the main body 10 matches the model of the electronic image forming apparatus can be referred to as embodiment one, and will not be described herein.

Of course, the fourth power receiving member 52 of the developing unit 2 may be controlled to extend and contract in other manners to engage the fourth power receiving member 52 with the first driving member 15, which is not limited herein.

Example four

The embodiment provides an electronic imaging device, which comprises a main body and a processing box detachably mounted in the main body, wherein a power receiving part is arranged on the processing box, a driving part capable of being meshed with the power receiving part is arranged in the main body, the power receiving part can push the driving part to move along the axial direction of the driving part relative to the main body when being meshed with the driving part, and a detection device is further arranged in the main body and determines whether the processing box is mounted in the main body or not by detecting the movement of the driving part, or the model of the processing box mounted in the main body is matched with the model of the electronic imaging device.

As shown in fig. 11, the first driving part 15 in the main body 10 is movable in the Y direction or in the reverse direction of the Y direction with respect to the main body 10. The first power receiving unit 23 includes a first power receiving member 24 and a first hub 25, and the first power receiving member 24 and the first hub 25 are connected by a universal joint, that is, the first power receiving member 24 can swing in any direction relative to the first hub 25. And when the first power receiving member 24 is swung from a position inclined with respect to the first hub 25 to a position where the rotational axis of the first power receiving member 24 substantially coincides with the rotational axis of the first hub 25, the distance between the end of the first power receiving member 24 in the Y direction and the first hub 25 increases from L1 to L2. Since the first boss 25 does not move in the reverse direction of the Y direction with respect to the first driving member 15, when the developing unit 2 is mounted in the main body 10 and the first power receiving member 24 swings from a position inclined with respect to the first boss 25 to a position where the rotational axis of the first power receiving member 24 substantially coincides with the rotational axis of the first boss 25 to engage the first power receiving member 24 with the first driving member 15, the first power receiving member 24 pushes the first driving member 15 to move by the H distance in the Y direction.

The present embodiment detects the movement of the first driving member 15 by the detecting means in the process of mounting the developing unit 2 into the main body 10 and engaging the first power receiving member 24 with the first driving member 15 by providing the detecting means for detecting the movement of the first driving member 15 in the main body 10, thereby causing the CPU to detect that the process cartridge 101 has been mounted into the main body 10.

Specifically, as shown in fig. 12, in the present embodiment, the detection device 401 includes an elastic member, a third conductive member 62, a fourth conductive member 63, and a detection member 45. Preferably, the elastic member is an elastic piece 61 having elasticity, one end of the elastic piece 61 is fixed to the side plate 19 on one side of the first driving member 15 in the Y direction, and the other end abuts against one end of the first driving member 15 in the Y direction. The fourth conductive member 63 is disposed on one side of the other end of the elastic piece 61 in the Y direction, the third conductive member 62 is disposed on the side of the side plate 19 opposite to the Y direction, and a projection of the third conductive member 62 and the fourth conductive member 63 in the Y direction at least partially overlap. The other end of the elastic piece 61 is pressed and then can move in the Y direction, so that the third conductive member 62 and the fourth conductive member 63 abut against each other. Compared with the arrangement mode of other detection devices, the design can enable the driving part to be more smoothly engaged. Preferably, an elastic material such as sponge or rubber is provided between the fourth conductive member 63 and the elastic piece 61 and/or an elastic material such as sponge or rubber is provided between the third conductive member 62 and the side plate 19, or the third conductive member 62 and the fourth conductive member 63 are directly made of an elastic conductive material, so that the other end of the elastic piece 61 can continue to move by a distance in the Y direction after the third conductive member 62 and the fourth conductive member 63 are abutted.

The detecting member 45 is connected to the third conductive member 62 and the fourth conductive member 63 by wires, respectively, and when the first power receiving member 24 of the developing unit 2 is not engaged with the first driving member 15, the detecting member 45 applies a voltage to the third conductive member 62 and the fourth conductive member 63 by a power source, so that a voltage difference exists between the third conductive member 62 and the fourth conductive member 63. When the first power receiving member 24 is engaged with the first driving member 15, the first driving member 15 is pushed by the first power receiving member 24 to move in the Y direction by a distance H, so as to press the elastic piece 61, so that the fourth conductive member 63 on the elastic piece 61 moves in the Y direction and abuts against the third conductive member 62, at this time, a conductive loop is formed among the third conductive member 62, the fourth conductive member 63 and the detecting member 45, that is, a current passes through the detecting member 45, and the detecting member 45 feeds a detected current signal back to the CPU, so that the CPU detects that the process cartridge 101 is mounted in the main body 10, or the CPU detects that the model of the developing unit 2 mounted in the main body 10 matches the model of the electronic imaging device. Therefore, the smoothness of the process cartridge in the process of being loaded into the electronic imaging device can be increased to a greater extent, and the process cartridge is prevented from being blocked due to the interference of the detection device on the process cartridge.

Of course, with the third power receiving unit of the second embodiment, when the power receiving member is engaged with the driving member by extending and contracting with respect to the hub, the first driving member can be pushed to move in the Y direction as well, and therefore, the process cartridge provided with the third power receiving unit can be applied to the solution of the present embodiment as well.

The above embodiments relate to a detection method for detecting whether a process cartridge is mounted in place in a main body of an electronic image forming apparatus or whether a model of a process cartridge mounted in the main body of the electronic image forming apparatus matches a model of the electronic image forming apparatus. The detection part on the detection device can detect the electric signal matched with the movement and transmit the electric signal to the CPU of the electronic imaging device to obtain that the processing box with the matched model is installed in place, so that whether the processing box is installed in place in the main body of the electronic imaging device or whether the model of the processing box installed in the main body of the electronic imaging device is matched with the model of the electronic imaging device can be confirmed by detecting whether the detection device receives the specified electric signal.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
